Beschreibung
Zusammenfassung:	This paper describes an implementation of data embedding within images utilising wavelet packet transform. This implementation is performed in two stages: (i) algorithm development and (ii) test. The first stage deals with creating image decomposition process and designing data embedding algorithm. The second stage deals with testing of the implemented technique for different images, under different noise levels and filtering. A discussion of experimental results is given.
